  Hard alloy tools utilize imported or domestically produced grades that offer high impact resistance and exceptional wear resistance.

  The blade material is made from high-performance air-hardening alloy steel, with a heat-treated hardness ranging from HRC40 to HRC50.

  Wear-resistant layers with a thickness of 3–5 mm are built up on key areas of the blade surface.

  The connection between the cemented carbide and the tool body is achieved using medium- or high-frequency brazing, or an inlay process, with silver-based or copper-based alloys serving as the brazing material.

  We offer universal scrapers and cutter picks suitable for use on tunnel boring machine (TBM) cutterheads manufactured by Herrenknecht, Mitsubishi, Komatsu, NFM, LOVAT, and others.

  Specialized teeth cutters, ripper blades, scrapers, and other tools can be designed and manufactured according to formation characteristics or user requirements.
